JNO. A. ROBSON, OF NEW YORK, N. Y.

SOFA-IBEDSTEAD.

Specication of Letters Patent No.

To all whom t may concern.'

Be it known that I, J oHN A. RoBsoN, of the city of New York, in the county and State of New York, have invented a new and useful Improvement in Sofa-Bedsteads; and I do hereby declare that the following is a full and exact description.

The nature of my invention consists in sliding the seat of the sofa out to the front, and dropping the upholstered part of the back (which is the same on both sides) out of the frame and toward the front, meeting and resting against the inner edge of the seat, thus forming a double spring mattress bed.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

I construct my sofa in any of the known forms with the seat sliding out to the front nearly its whole width; the back of my sofa is upholstered on both sides, the front down even with the top of the seat, and the back down its entire width, bringing it even with, and on a level with the seat of the sofa when formed into a bed, which upholstered part of the back being independent of its frame is thrown forward, out of it, toward the front, so that the upper edge of the back rests against the back edge of the seat, when drawn out to the front, as represented in Figure A in the accompanying drawing, thus forming a double mattress bed, with, or without springs, and without moving any portion of the frame of the sofa, or removing the sofa from its position. That part of the back which lets down to the front, rests upon pivots which set loosely in sockets to lit, so that it can be entirely detached from the frame, as represented at Fig. B in the accompanying drawing.

The front piece or molding which is made to cover the front legs, as represented at Fig. C in the accompanying drawing is made fast to the seat, and drawn out with it, as exhibited at Fig. A in the accompanying drawing, the upholstered part of the back, when in its upright position, is kept from falling out of the frame to the rear,

by slight projections at each end resting against the front part of the frame of the back of the sofa, but it can be so kept by many other means; it is also when in that position kept from falling forward, by the back edge of the seat pressing against its lower edge immediately under the upholster-ing of the front part of the back, when the seat is placed in its proper position to be used as a sofa, and also by upholstered end pieces, with the inner sides made hollow and to fit over head and foot boards, or small arms made fast to the ends of the seat, these upholstered end pieces are made of the proper shape to fit, and are slipped over these head and foot boards, or small arms, and catch in recesses made for that purpose on the inner sides of the end of the sofa frame, which keep them firmly in their proper positions, and which forms the com* plete sofa as represented by letter A at Fig. C in the accompanying drawing, they are easily removed by small loops attached to their lower edges, they also assist in keeping the seat from running out to the front, when used as a sofa, and also keep the back in a firm upright position; this makes a complete finish'to the sofa, and holds all of its parts lirmly together, making a handsome and neat sofa, without the heavy clumsy appearance of the ordinary sofa bedsteads, having at the same time an opening, or space, under the seat suticiently large to hold all the necessary bedding ordinarily required, and when set upon castors looks neat, and is of the ordinary height of comfortable sitting sofas.

lVhat I claim as my invention, and desire to secure by Letters Patent, is-

The letting of the upholstered part of the back fall forward to meet and rest against the rear, or back edge of the seat to form the bed, without moving the sofa from its place, or disturbing any part of the frame, as described.
